SPA525 phones compatible with 2921 CME?

[sethschmautz]

This is only about 50% a Small Business question, but does anybody happen to know whether it's possible to use an SPA525G phone with an ISR 2921 w/ CME?  I have a client that is looking to upgrade from a UC540 to a 2921 and they want to hold onto their 525Gs if possible.  Any help would be greatly appreciated.

Thanks,

Seth

Sadly, they are not supported natively. But they should work as third-party SIP-phones. I'm not really sure if the functionality is still good then.
